This book provides a clear theoretical contribution on the basis of the electrocardiogram including heart vectors and territories therefore very interesting to then understand the different pathologies and their EGC plots Too bad the questions put to the reader have the answer on the same page, it wastes a little reflection. And will detect even few mistakes between plots of bradycardia and tachycardia so pay attention! This book is for people who already have some knowledge in cardiology (nursing students, nurse ..)
